LOS ANGELES -- If Lamborghini makes a coupe, you can be sure a topless version is coming as well. Sure enough, the Italian supercar-maker has revealed a roadster version of its Aventador LP700-4.

And, of course, it's fast: the Aventador Roadster will accelerate from 0-100kph in less than three seconds, with a maximum speed of about 350kph, the automaker claims.

The roadster's two-piece carbon-fiber roof uses patented technologies, with each half of the roof weighing less than 6kg and fitting in the front luggage compartment.

The B-pillar provides support for the removable roof, engages a rollover protection system for occupants and still allows ventilation for the mid-mounted engine.

The Aventador Roadster is fast.

The powered rear windshield not only influences the flow of air into the vehicle, but also controls how the car's occupants hear the shriek of the 6.5-liter, 700hp V-12 engine. No matter how the rear windshield is aligned, the wind deflector will keep occupants' hairstyles muss-free, Lamborghini says.

Orders can be taken immediately for 2013 deliveries. For those worried about their car budget, the U.S. starting price, before taxes and destination charges, is $381,360 (300,000 euros).
